General description This machine is of the class in which are arranged side by side, in successive denominational order, a series of sets of actuating, accumulating and recording devices; each set comprising an adding wheel, its cooperating printing devices, a row of nine digital setting keys which may be set for controlling without actuating said adding and printing devices, an actuator for actuating the adding and printing devices according to the setting of said keys, and cooperating devices for carrying from a set of one denomination to another of the sets; and which machine is also provided with a universal oper ating mechanism for causing simultaneous actuation of said adding and printing devices by their respective actuators.

Each row of keys is provided with a stop bar 289 (Figs. 25 and 54) upon which is formed a
